Hull in AutoCAD => Wilderfire 2

[rvt3d]

Hey All,

I have WF2.0 currently installed. I am a newbie, but I am patiently...
So I have a sideview, top and front view of a line plan for the hull of a ship.

Now I need these line with reference point into WF. I have been trying to do all sorts of things but no real luck yet. Mostly what I tried is Shared data -> from File to get information into PRO/E but failed because the DXF I have contains everyhting, I do see the layers but I am a little list to get each layer out, make a sketch from it to place a surface on it later on.

Any hints/tips on this?

Note: I have done something simular for a model airoplane, but that was just from a TIFF I could trace.

I have often inserted sharded data and got the same troubles, what I tend to do is break the drawing down into sections and add small amounts at a time.Wildfire sketcher doesnt like it when you give it too much to do, the lesser amount of lines the better.

Make sure that the DXF that you are importing does not have any polly lines. Also, make sure that every thing is on zero elevation.

I am getting a bit closer already....
I MUST have autocad 2000 DWG drawings and I exported every line 'block' seperatly.
I started of creating seperate sketches of every deck seperatly. This seems to work now.

When it's fully imported I'll post the 3D...

OPEN THE DRAWING AS A .PRT FILE THEN WORK ON IT. ITS VERY EASY,FAST & SIMPLE. LATER CHANGE THE UNIT

Hi All,

I am slowly getting there (I only work on it 1 hour a day...)
Here are some results. I am off with my reference still but I think that's easy to correct.

I exported every single line by line. Importing the whole cad as a part doesn't help me much.

Hi again rvt3d,


I have noticed that autocad data is often not too accurate, hence the problems when inserting into sketcher. If the lines are not perfect then you get problems, I also tend to Purge every layer before I import to pro-e. Keep it as simple as possible.


I do not think you should be inserting these line by lines though, very tedious if you have many to do, surely thats just as easy to create them as sketches from scratch ?

I have to do it line by line, so I am sure there is not anything else in the file. I simple use export -> block. Then convert the DWG back to AutoCAD 2000 format. AutoCAD2004 can't be read by WF2 I wound out.

Re-creating the lines is not an option since it defines the hull fairly accurate (apparently not accurate enough but you are right.. it's just AutoCAD).

A simple solution to accuracy problems from autocad is to use autocad to change each line into a series of points. You have many options to import points into proE. You can also quite simply shoot a 3D spline curve through the points.


Saving your file as an Iges rather that a dxf can give you more options as well. You can than more easily import it onto a coordinate system that you can create ahead time to move and rotate the curves. Usually you can than start a sketch and simply copy the curves you want onto each plane!


Depending on what you are working on, usually the hull designs (or aero if it is an airplane)can come up with mathematical expressions for the shape they want. You can use an equation to create a line exactly!

As promissed an update,

I imported the autoCAD lines lines by line, some converting the spline and some not, others I re-traced them myself.

Then basicly re-created the hull from scratch with these lines.
The lines are now a good reference (but don't want to use them as such) to create a surface.
Any suggestions for creating a surface that will initlially match my lines but with the posibility to change the surface without touching my reference? (did I make myself clear here?)

THis why I can do surfacing (I thinki) using control points and lator I can see how much off I am from my origional lines.
